The second part of the doctoral research used compositional remote sensing data to search the whole Moon for exposures of HA mare basalts, or areas where the regolith consists mainly of material derived from HA basaltic flows. They represent the oldest sampled mare basalts, and the return of HA basalt samples from four locations, separated by 2400 km, implies they may be widespread on the Moon.	cache/08612n51j94.txt	txt/08612n51j94.txt
